The ridge is where the hip bars and glazing bars meet at the top of a lantern, usually under a moulded or pressed end cap. Send photos from King's Lynn (PE30) and we'll tell you which it is — with the price agreed in writing before any work.
What you might be seeing
- A cracked or faded ridge end cap
- Sealant around the ridge cap split or missing
- Staining along the hip bars inside
What usually causes it?
Movement at the junction
Several bars meet at one point and each moves slightly with temperature; the seals at the ridge take the strain.
Poor original sealing
Ridge details are fiddly. If the original sealing was rushed, it's often the first place to leak.
Roof lanterns in King's Lynn
Drier, sunnier parts of the UK are kinder to seals than the wet west, but strong sun ages sealant, gaskets and plastic end caps, and south- or west-facing lanterns can make rooms very warm. Solar control glass and an opening vent help.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.

What should you expect to pay in King's Lynn?
Typical range: £195–£445 ex VAT, which is £234–£534 with VAT, per lantern. Towers or scaffold, where needed, are priced into the quote. Your fixed price is confirmed in writing before any work starts.
Do you need permission in England?
In England, like-for-like repairs to a roof lantern don't usually involve building control. A full replacement or a bigger opening is controlled under the Building Regulations 2010, so we set out the route in writing first. Listed buildings need listed building consent from the local council for alterations, and conservation areas can have extra controls; like-for-like repairs are treated differently from changes, so check with the council's conservation officer first.
